What does it mean to say turn right, stop and start at the back of the big truck?

When turning right, the big truck will stop first, then restart, and then turn right. It is mainly to remind motor vehicles, non-motor vehicles and pedestrians behind and on the right side of large trucks to keep a safe distance when turning right, and not to get too close.

Reasons why large trucks need to stop before turning right:

When the truck turns right, the blind spot on the right side is very large. It can be said that when a large truck turns, it can hardly see the right side of the vehicle, and often the motor vehicle or non-motor vehicle driving on the right side of the truck is dragged under the wheel because of the inner wheel difference.

After the truck stops, it can better observe the situation behind the right side of the vehicle, and can also remind the vehicles driving on the right side, which can protect the safety of non-motorized pedestrians on the right side. Many freight companies stipulate that turning right must stop for 5 seconds before driving.

Extended data

When you get too close to a big truck, there are two dangerous points:

First, the blind spot, the bigger the truck body, the bigger the blind spot, and it is difficult for drivers to find cyclists in the blind spot.

The second is the inner wheel difference, that is, the turning radii of the front wheel and the rear wheel are different during the turning of large trucks, resulting in the inner wheel difference. If you ride close to a big truck, even if you avoid the front wheel, you may not be able to avoid the rear wheel, which may cause danger.

Safety tip: When large trucks approach, try to stay away, keep a horizontal distance of more than 2 meters, and avoid long-term parallelism; If you find a big truck turning right, stop immediately and avoid it in the direction away from it.
